<p>This part of ISO 22262 specifies methods for sampling bulk materials and identification of asbestos in commercial</p>
<p>bulk materials. This part of ISO 22262 specifies appropriate sample preparation procedures and describes in</p>

<p>This part of ISO 22262 also specifies simple procedures for separation of asbestos fibres from matrix materials</p>
